Thanks, mate. I'll just keep them until I can use one to fulfil a request.
I've not done anything more with the Ultima V disk and those new images I downloaded yet. I've been busy with other things for the last couple of days, but I might get a chance to look at it tomorrow. I'm picking up an Acorn A5000 Computer to add to my collection tomorrow, so it will depend on how that goes. If not, I'll give it a go at the weekend. That disk is really in the last chance saloon now!
If you've got any other disks you'd like to send, you know you're always welcome!
